Lessons About Our Environment from the World's Oldest Living Things
"It is well that you should celebrate your Arbor Day thoughtfully, for within your lifetime the nation's need of trees will become serious. We of an older generation can get along with what we have, though with growing hardship; but in your full manhood and womanhood you will want what nature once so bountifully supplied and man so thoughtlessly destroyed; and because of that want you will reproach us, not for what we have used, but for what we have wasted."--Theodore Roosevelt

Trees have been essential to the success of human beings, providing food, shelter, warmth, transportation, and products. Trees are also necessary for a healthy atmosphere, literally connecting the earth with the sky. Once in wild abundance, trees have receded as we have clearcut the landscape in favor of building cities and farms, using up and abusing our forests in the process. Over the centuries, we have trained food trees, such as peach and apple trees, to produce more and better fruit at the expense of their lives. As Jeff Gillman, a specialist in the production and care of trees, explains in How Trees Die: The Past, Present, and Future of Our Forests, the death of a tree is as important to understanding our environment as how it lives. While not as readily apparent as other forms of domestication, our ancient and intimate relationship with trees has caused their lives to be inseparably entwined with ours. The environment we have created--what we put into the air and into the water, and how we change the land through farming, construction, irrigation, and highways--affects the world's entire population of trees, while the lives of the trees under our direct care in farms, orchards, or along a city boulevard depend almost entirely on our actions. Taking the reader on a fascinating journey through time and place, the author explains how we kill trees, often for profit, but also unintentionally through overwatering or overmulching, and sometimes simply by our movements around the globe, carrying foreign insects or disease. No matter how a tree's life ends, though, understanding the reason is essential to understanding the future of our environment....

Can beer make plants grow? How about buttermilk? Or music—classical or rock? Are you sure about planting trees in deep holes? And how about chasing insects with hot sauce and stopping slugs with eggshells?

Whether in ancient books, on television, or in gardening publications, remedies for all your garden woes are here for the taking: the challenge is to know what will work and what won't.

Fearlessly conducting original experiments and harvesting wisdom from the scientific literature, horticulturalist Jeff Gillman assesses new and historic advice and reveals the how and why‚ and sometimes the why not‚ for more than 100 common and uncommon gardening practices. The results will surprise even experienced gardeners....

Gardeners tend to assume that any organic product is automatically safe for humans and beneficial to the environment—and in most cases this is true. The problem, as Jeff Gillman points out in this fascinating, well-researched book, is that it is not always true, and the exceptions to the rule can pose a significant threat to human health. To cite just one example, animal manures in compost can be a source of harmful E. coli contamination if imporperly treated. Gillman's contention is that all gardening products and practices—organic and synthetic—need to be examined on a case-by-case basis to determine both whether they are safe and whether they accomplish the task for which they are intended.

Ultimately, Gillman concludes, organic methods are preferable in most situations that gardeners are likely to encounter. After reading this eye-opening book, you will understand why, and why knowledge is the gardener's most important tool.
